IMPROVEMENT IN SAWING-MACHINES.

Specification forming part of Letters Patent No. 149,311., dated April7, 1874; applicaticn filed May 16, 1873.

To all 'whom it may concern:

Be it known that I, WILLIAM HEAYSMAN, of the city of Chicago, in thecounty of Cook and State of Illinois, have invented certain new anduseful Improvements in Sawing-Machines for sawing, shaping, sticking,Ste., of which the following is a full description, reference being hadto the accompanying drawings, consisting of two sheets, making a part ofthis specification, in which- Figure l is a side elevation with aportion of the frame removed; Fig. 2, a planview with the table and aportion of the upper part of the machine removed; Fig. 3, an end view ofthe upper part of the machine which supports the vertical saw; Figs. 4,5, and 6, details showing the mode in which the upper end of thevertical saw is secured; and Figs. 7 and 8, two views of the verticalsaw.

The object of my invention is to construct a combined machine designedchiefly for the use of small manufacturers, by means of whichscroll-sawing, work usually done by circular saw, shaping and sticking,and similar operations, can be performed.

In the drawings, A represents the several portions of the frame of themachine; A1 A2, two uprights at the rear of the machine upon thecross-bar, at the top of which is located a bar, B, the outer end ofwhich is supported by a brace, C, to which the head for the vertical sawis secured. D is a shaft at the rear of the machine, upon one end ofwhich is a drivingpulley, E, having three grooves, a b c, for thereception of three separate driving-belts. At the other end of thisshaft is a driving-pulley, F. J is a shaft, upon which are threepulleys, G H I. l are two vertical shafts, on each of which is a pulley,L. On each shaft is a collar, n; and the upper end, m, of each of theseshafts is so formed that suitable knives or cutters, for cuttingmolding, can be placed there- .operated upon by the toolsV on c.

is formed so as to receive such tools as may be required. This shaft hasa driving-pulley, k. M is a table, placed upon the side of the machineto receive the work which is to be This table may be so connected withthe machine that it can be adjusted vertically. This can be done byattaching to the sides of the machine bars N, each having a slot, g,therein to receive the pins placed upon the brackets upon which thetable M rests, the same being held by the nuts n. Only one of thesebars, N, with the slot g, is represented. q is a shaft located insuitable bearings near the lower portion of the fram e, on the outer endof which is a crank-wheel, It, for the purpose of driving the verticalsaw Q. This shaft q has upon it a iiXed driving-pulley, l?, and a loosepulley, p, may be used to receive the driving-belt when the saw Q is notin use. All of the bearings of these several shafts may conveniently bemade similar to that represented at t. The head with which the upper endof the vertical saw is connected is composed of two pieces, h z'. Theupper end of h is permanently secured tothe bar B, and the part t' has aslot in the upper portion iitting over the piece h, to which it issecured by means of pins passing through the holes c, and this part ican be adj usted vertically by means of these pins and holes. j, Figs. 3and 6, is a block running in a groove provided for it in the frontportion of the head i, to the lower end of which block j theupper end ofthe saw Q is connected, and to the upper end of the block is secured arod, 1^, which is connected with a spring, s, suitably connected withthe part c. The spring s may be a rubber spring, or might be a coilmetal spring. The lower end of the saw is connected to a block, y,moving in a suitable groove, as usual. The upper and lower ends of thesaw are formed as represented in Figs. 7 and 8; and this saw is notpermanently connected at its upper and lower ends to the machine; butthe hooks are simply passed over pins connected to the blocks j and y.The action of the spring s holds the saw in position, prevents it fromslipping off from the pins with which it is connected, and aids inreturning it and the block j to the position shown in Fig. 1, after adownward stroke of the saw. This construction of the saw furnishes avery ready means of removing it. The hooks m are formed from the sameplate as the rest of the saw, the same being turned one-half round andbent over, as represented.

It is not designed to use the circular saw and perpendicular sau at thesame time. Either one can be removed When the other is -in operation.

By means of cutters placed upon the tops m of the shafts l, moldings andiutings for various purposes can be made. By .means of suitable toolsplaced upon the end e of the shaft K., sticking, tonguing, grooving,matching, fluting, and boring can be done, the material operated uponbeing placed on the table M, Which is adjustable. As the parts are anranged the shaft K is driven by a belt placed in the central groove I)on E. The reciprocating saw is driven by a belt located in the groove con E, and passing` over the pulley I?. The shaping-knives upon the topsm of the shafts l are driven by tivo belts, one of which passes over thedrum I and one of the pulleys L, and the other over the drum H and theother pulley L, Which drums, H and I, are driven by a belt in the groovea on E, which passes over the pulley Gr. The shaft K and the shafts Zcan readily be removed from the machine when not required. The cuttersupon the end of the shaft K, and those upon the shafts Z Z, can beoperated at the same time, if desired.v

The Whole machine can be operated by hand, a crank-pin being placed uponthe drum F; or the same can be driven by power applied through a belt t0the drum F.

What I claim as new is as follows:

In a machine, substantially as described, the arrangement of the saws Qand d and shafts L, With heads m for cutters, and the operativemechanism, all constructed and arranged for operation, as and for thepurpose herein set forth.

VILLIAM HEAYSMAN.
